Several dozen dark olive green Olivenite crystals infest what I believe to be a Goethite matrix on this specimen. These crystals almost remind me of vivianite, with their curved form and pearly to vitreous luster. The crystals dull translucence is difficult to see because the crystals do not tend to grow outwards from the host rock. They do not exceed 1/4"(6 mm) in length, and most of them inhabit rough depressions in the host rock and some crevices along the specimen's edge.
